mounting ballasts on wood

'Lo there.
Someone wrote in last week (I think) asking about the safey of mounting
electronic ballasts on a wooden base. I was going to respond at the time,
but things didn't work out.
If the ballasts are actually electronic ballasts for 4-foot tubes they
shouldn't get very warm in operation and you should be able to mount them
safely on wood. If they are magnetic ballasts instead, then you might
want to mount them on a metal base.
I used electronic hybrid ballasts and mounted mine on a wood base with
aluminum flashing fashioned as a heat sink to protect the wood. Once I
actually got things working I found that the ballasts ran cooler than
the tubes themselves. Next time I'll just mount directly to the wooden
base.
